T0 all whom t may conce/m.' I

Be it known that NIELs NIELsEN, citizen of the United States, residingr at Lincoln, in the county of Lancastery and State of Nebraslra, has invented certain new and useful Improvements inEngine-Supporting Stands, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to engine supporting stands, and has for its object to provide a device of this character constructed in such a manner that an internal combustion engine of the automobile type is supported on a pivoted frame, which frame has its ends provided with pintles rotatably mounted in axially aligned bearings of a rigid frame, thereby allowing the pivoted frame, which supports the engine, to be turned upside down or at any angle according to the position desired by the repairman.

A further object is to provide one of the pintles with a worm gear, with which worm gear a worm carried by an operating shaft supported in bearings of the rigid frame en gages, and forming means whereby the pivoted frame may be easily and quickly positioned at various angles.

A further object is to provide one of the pintles with a longitudinally disposed bearing for the reception of a drive shaft carried by a supporting frame adjacent the stand, which frame is preferably fixed to a permanent base, and the shaft provided with a. pulley which may be driven from any source of power. Also to provide a drive shaft and stand with clutch means whereby the drive shaft may be rotated as desired. The inner end of the drive shaft is provided with mgeans for engaging the engine crank shaft, thereby allowing the engine to be operated while supported on the pivoted stand.

A further object is to provide the pivoted stand with outwardly and inwardly adjust able spaced bars, which bars may also be adjusted upwardly or downwardly, thereby allowing adjustment for the engine crank shafts of various types of engines in axial alignment with the drivev shaft extending through the pintle of the frame.

With the above and other objects in View the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and 'crank shaft and supported on the pivoted frame.

Referring to the drawings, the numeral 1 designates the rigid frame of the stand and 2 the pivoted frame, pivotally mounted in the rigid stand. The rigid frame 1Comprises spaced triangular shaped members 3, which members are rigidly held in spaced relation by tie-rods 4, which rods extend through the triangular shaped members 3, and through tubular members 5. The tubular members 5 maintain `the triangular shapedJnembers 3 spaced from each other, and when the nuts 6 carried yby the tie-rods are tightened, a rigid frame is formed. The frame 1 is preferably supported on casters 7 thereby providing means whereby the device as a whole may be moved from place to place as desired.

The pivoted frame 2 comprisesl transversely disposed bars 8 in parallel relation to each other, which bars are provided with upwardly extending arms 9. Extending outwardly from the arms 9, and in axial alignment with each other are pintles'll and 12, which pintles are rotatably mounted in bearings 13 in the upper endsof the triangular shaped members 3. It will be seen that the pivoted frame may be moved entirely around the vertical transverse plane, thereby allowing, the internal combustion engine 14, which is supported 'on the supporting rails 15, to be positioned in any position desired according to the desire of the workmen.t For instance if repairs are being made to the underside of the engine, the engine may be turned entirely over, and so supported as long as desired by the workmen. The side rails are formed from spaced bars 16, which bars are held in parallel relation by means of bolts 17 which pass through the ends of the bars 15 and through vertically disposed slots 13 in the plates 19 carried by the collars 20, It will be seen that the bars 16 may be adjusted upwardly or downwardly and that the collars 20 may be adjusted outwardly or inwardly on the bars 8, thereby allowing said bars to be adjusted for receiving bolts 21, which pass through the engine supporting arms 22, and between the spaced bars 15, according to the type of engine being supported. rThe collars 20 may be held on the bars 8 by set screws 23, however other conventional means may be provided if so desired. It will be seen that the bars 16 may be adjusted upwardly to a position where the crank shaft 24 of the engine 14 will be in axial alignment with the pintle 12, thereby allowing a drive shaft 25, which is rotatably mounted in a bearing 26 of thepintle 12, to be connected to the crank shaft 24 of the engine by means of a detachable head 27 carried by the drive shaftj25, which head is slotted as at 28 and receives in a chamber 29 thereof the outer end of the crank shaft 24, said crank shaft being provided with the usual transversely disposed pin, which is received in the slot 23, said slot and pin connection being of conventional form used in engine cranking mechanism. The drive shaft extends outwardly and is rotatably mounted in bearings 31 of a stand 32, and rotatably mounted on the shaft 25 is a conventional form of drive pulley 33 driven from any suitable source by means of the belt 34. Slidably mounted on a key 35 of the shaft 25 is a clutch member 36Which clutch member cooperates with the female clutch element 37 of the drive pulley 33, and when in engagement causes the drive pulley and the shaft 25 to be locked together in such a manner that the drive shaft 25 will revolver with the pulley 33, thereby imparting power to the crank shaft 24 of the engine, and operating the engine. By providing means for operating the engine the repairman can test the engine, or move the partsA to positions where they can be easily reached and repaired.

v The outer end of the pintle 11 is provided with a wormy gear 37, which is keyed to the pintle 11 at 39. Rotatably mounted in bearings 4() of outwardly extending arms 41 of one of the end members 3 is a transversely disposed shaft 42, which shaft is provided with a worm 43, which meshes with the underside of the worm gear 38, said worm being pinned at 44 to the shaft 42, and when rotated by the operatingwheel 45 causes the worm gear to be rotated and consequently causes the pivoted frame 2 to tilt to the desired angle. fter the iframe 2 has been tilted to the desired angle, it will be seen that it. will be held in position simply by the worm 43, the pitch of which is low.

From the aboveit will be seen that an engine supporting stand is provided, which is simple in construction, the parts reduced to a minimum and the engine may be positioned in any position desired. Also that means is provided for operating the engine no Inatter what position it is in on the pivoted frame 2, thereby allowing the operator to move the engine or operate the same while in various positions.

llhe invention having been set forth what is claimed as new and useful is 1. An engine supporting stand comprising a rigid frame, a frame pivotally mounted in said rigid frame, means for supporting an engine on the pivoted frame, outwardly extending pintles carried by the pivoted frame and rotatably mounted in bearings of the rigid frame, a worm wheel carried by one of said pintles, a worm meshing with said wheel, said worm being mounted on an operating shaft carried by the rigid frame, and means extending through one of the pintles whereby the engine on the pivoted frame may be operated through its crank shaft when in various positions.

2. The combination with an engine supporting stand comprising a rigid frame and a pivoted frame, said pivoted frame being supported by pintles mounted in bearings of the rigid frame, of a shaft extending through one of said pintles and adapted to cooperate with the crank shaft of the engine on the pivoted frame and forming means whereby said engine may be operated.
